PREFACE P-1

General Information Application of the Consistometer

Cements have numerous applications in the drilling, completion, work-over, and abandonment of wells. For each application, the cement is designed with special properties and is given additives that provide predictable slurry density, volume, viscosity, compressive strength, and thickening time. Thickening time, or the time a cement slurry remains able to be pumped into the well, is one of the most critical properties in designing a slurry. A short thickening time is desired, while maintaining the special properties of the cement's design. The thickening time of a slurry can be measured in a laboratory by testing a sample of the slurry in a Pressurized Consistometer. The elapsed time between an initial application of pressure and temperature on the slurry sample and the development of 100 Bearden units of consistency (Bc) is the thickening time for the sample at a particular specification test schedule [Table 8.2, API Spec 10(1)].

Description of Apparatus The Model 7322 is designed so that closure, heating, and pressurization can be achieved quickly. The pressurized consistometer incorporates a rotating, cylindrical slurry cup equipped with a stationary paddle assembly enclosed in a pressure chamber designed for a working pressure of 154 MPa (22,000 psi) at a maximum temperature of 205°C (400°F). An air-operated hydraulic pump generates pressure to the cylinder assembly. The hydraulic system incorporates a reservoir, piping, valves and filters. Heat is supplied to the chamber by a 2200-watt, internal, tubular heater. Thermocouples are provided for determining the temperatures of the oil bath and cement slurry. The programmable temperature controller automatically controls the rate of temperature rise (i.e. temperature gradient). When the slurry reaches the desired temperature, the controller will hold the temperature at that level. Hydraulic pressure is generated with an air operated high-pressure pump. Pressure settings are maintained through the control of a pressure relief valve and air pressure available to the pump. The slurry container is rotated at a constant speed of 150 +/- 15 rpm by a magnetic drive. Drive torque is transmitted from a set of outside drive magnets, through a non-magnetic housing, to permanent magnets attached to the rotating shaft within the cylinder. Permanent, rare earth magnets are used to ensure high torque and a long magnetic-field life. The viscosity (i.e. consistency) of the cement slurry is recorded on a chart as BC (Bearden Units) obtained from a potentiometer installed within the pressure cylinder. The potentiometer contains a standardized torsion spring, which resists the rotating force of the paddle. Rotational force is proportional to consistency of the cement slurry.

P-2 PREFACE

In the Model 7322, pressure is controlled using a dynamic, programmable pressurization system. The temperature, pressure and the viscosity of the slurry are recorded on a strip chart in the electronics module. An interface is also included for PC based data acquisition. The Chandler Model 5270 Instrument Control System is specifically designed for this interface. Using the Model 5270 software, hesitation squeeze treatments can also be simulated using the programmable motor and pressure control capabilities.

To allow the 5270 DACS software to control the motor, place the motor switch AUTO position. Refer to the 5270 online help files for detailed information on setting up hesitation squeeze schedules. API Slurry Cup Preparation

For an accurate thickening time test to be performed, it is important for the slurry cup to be properly maintained and prepared. The following procedure should serve as a guideline for slurry cup preparations. While assembling the slurry cup, refer to drawing 07-0031 in the Drawings section of this manual. 1. Thoroughly clean all parts and verify that all parts are in good condition. 2. Lightly grease all interior surfaces of the slurry cup with white lithium grease or the

equivalent. 3. Install the diaphragm support ring, the diaphragm, and the diaphragm backup plate onto

the paddle assembly. The diaphragm should be oriented so that the larger brass piece is at the top.

4. Slide the shear pin assembly onto the paddle shaft. Place the potentiometer mechanism on

the paddle shaft until it seats. Using an Allen wrench, align the shear pin assembly into the bottom of the potentiometer mechanism and tighten the set screw to secure it in place. Remove the potentiometer mechanism from the paddle shaft.

Diaphragm Support Ring

Diaphragm


5. Install the complete paddle assembly into the slurry cup. 6. Screw the diaphragm lock-down ring into the top of the slurry cup while checking to

make sure the paddle turns freely. 7. Invert the slurry cup into the slurry cup support. 8. Prepare the cement slurry in accordance with API Spec 10. Caution: According to API specs: The cement has to be under test (under pressure)

within 5 minutes of mixing. 9. Fill the cup with prepared cement slurry to the bottom of the threads. 10. Remove the plug (pivot) from the center of the bottom cap. 11. Replace the bottom cap without the plug. Slowly screw the cap into place and add

cement through the hole if required. 12. Grease the plug and replace. 13. Rinse the exterior surfaces of the slurry cup.

Running a Test 1. Remove the test cell plug, if it is not already removed from a previous test. 2. Attach the long bail through the holes on the top of the prepared slurry cup and insert it

into the test cell, rotating it until the bottom pins engage the cup drive table. Remove the bail.

3. After the slurry cup is loaded into the cell, the potentiometer mechanism (pot. mech.) is pushed onto the slurry cup paddle shaft and the test cell contact pins. Attach the short bail to the top of the potentiometer and lower the pot mech into the test cell. When properly engaged, the top of the paddle shaft will be flush with the top of the torque measurement potentiometer bearing. Remove the bail.

4. Check to be certain that the slurry cup and pot mech are properly engaged. Turn the Motor switch to ON. No rubbing noise should be heard.

Shear Pin Assembly


5. Screw the test cell plug into the cylinder by hand. The last turn of the plug seats the O-Ring seal and will offer slight resistance.

Note: Do not over-tighten the test cell plug. Hand-tightening the plug is sufficient

for a complete seal. 6. Slide the thermocouple through the test cell plug into the slurry cup paddle shaft. Start

the threads of the sealing gland into the test cell plug, but do not tighten the thermocouple at this time. Verify that the thermocouple is plugged in at the rear of the instrument.

7. Next, fill the test cell with oil. To accomplish this, close the Pressure Release Valve, and turn the CYLINDER Control Valve to the FILL position. When oil escapes from the top thermocouple high-pressure fitting, tighten the sealing gland with a 5/8” wrench.

8. Turn the Pump Switch to the AUTO position to apply the initial pressure to the test cell. When the pressure reaches the desired level, turn the Pump Switch to the OFF position. Adjust the pressure as required throughout the test by turning the Pump Switch to FILL to increase pressure or by slowly cracking open the Pressure Release Valve to relieve pressure. Use care to open the Pressure Release Valve slowly when attempting to bleed pressure.

9. To begin the test, the Temperature Controller and Pressure Controller programs must be started as follows.

10. Press the Advance Key to display the Control Mode (AUTO, OFF or MAN). Press the

Up or Down keys to select AUTO. Press the Infinity Key to return to the main screen. Press the EZ1 button to start the program. The “1” light should begin flashing indicating the control output to the heater and or pump.

11. Turn the Heater and Pump Switch to the ON position, and start the timer. (The heater and pump will not start until the program start up is initiated through the controller.)

Note: Turn the coolant control switch to ON if an external chiller is used. After the final temperature is reached for the schedule being run, the controller will continue on a programmed soak until the schedule is completed. Note: Once a program has been entered into the controller it may be reused by

pressing the EZ1 button to run the program again.

After the Test is Complete A buzzer will sound, signaling the slurry has reached the required consistency. The controllers must now be shut down as follows:

1. Turn the alarm switch to ‘Off.” 2. Press the Infinity Key on the consistency display to reset the alarm condition. 3. Set the heater switch to ‘Off.” 4. If the profile status light is displayed on the temperature or pressure controller screen,

press the EZ1 button to stop the profile and place the controllers in OFF mode (OFF will appear on the lower display).


5. If OFF does not appear in the lower display, press the Advance Key to display the

Control Mode (AUTO, OFF or MAN). Press the Up or Down keys to select OFF. 6. Start cooling the cylinder by placing the Coolant Switch to the ON position. Allow the cylinder to cool to 190º F (90º C) or less before continuing to the next step. The following steps are necessary in order to transfer the hydraulic oil from the pressure cylinder back into the reservoir. When cool-down is complete, set the pump switch to ‘Off.’ Warning: When the temperature of the sample is above 212°F, leave at least 500

psig on the sample during cool-down. Warning: If the cylinder is opened while its temperature is above 100°C (212° F),

steam will escape, and the operator can be injured! Be sure the cylinder temperature is below 100°C (212°F).

Draining the Test Cell of Oil

After the cell has cooled and all of the pressure has been relieved, perform the following steps to drain the oil. 1. Open the T-handled manual pressure release valve to relieve pressure in the cylinder

(slowly opening and closing the valve to release pressure in increments will prevent rupture of the slurry cup diaphragm).

2. Set the “Cylinder” control rocker switch to the ‘Drain’ position to transfer the oil from the cylinder into the reservoir. (Completion of the oil transfer will be indicated by a bubbling or hissing noise in the reservoir.)

3. Set the “Cylinder” control rocker switch to the ‘Off’ position to stop the oil transfer. 4. Loosen the thermocouple seal gland to vent the remaining air pressure from the cylinder. Warning: If the cylinder is opened while its temperature is above 100ºC (212 ºF), steam

will escape, and the operator can be injured! Be sure the cylinder temperature is below 100°C (212°F).

5. Remove the thermocouple from the cylinder head. 6. Remove the cylinder head by tapping the cylinder head handles with a rubber mallet to jar

the head loose and then remove the head itself. 7. Using the pot mech bail, reach into the cylinder and remove the pot mech. 8. Using the slurry cup bail, reach into the cylinder and remove the slurry cup. The cup

should be immersed immediately in a container of cold water. 9. Clean the slurry cup thoroughly and coat it with grease. Also, disassemble and clean the

diaphragm hub and apply grease liberally to the hub O-rings.

SECTION 3 – MAINTENANCE 3-1

Section 3 - Maintenance The operating life of the consistometer can be extended measurably if operating and maintenance instructions provided in this manual are adhered to. Avoidance of down time and parts replacement depends on the proper cleaning, lubrication, replacement of filters, and calibration of instrumentation and controls. The following procedures will correspond with the maintenance schedule time intervals included in this manual.

Chillers Instruments using a chiller sometimes produce condensation when used. The use of a fan or air conditioned environment will help in keeping the moisture level lower. Wipe away any condensation that may occur inside the cabinet.

After Every Test Pressure Cylinder

1. Inspect and replace the O-ring on the cylinder plug if cuts, damage, or imbedded particles are present. If none of these conditions are noted, wipe the O-ring and the plug groove free of cement particles or other foreign matter and lubricate the O-ring with a light film of grease or oil.

2. The thread of cylinder plug has been lubricated with molybdenum disulfide grease by the factory. If molybdenum disulfide grease is not immediately available, a mixture of white lead and lubricating oil will be a satisfactory substitute.

Potentiometer Mechanism

The potentiometer mechanism (pot mech) must be cleaned after every test. Using a nylon brush, lightly brush down the unit with mild dish washing soap. Clean all cement sediment from the contact springs, resistor, and exterior surfaces. Rinse the assembly thoroughly with water. Apply a light coat of mineral oil to the resistor surface and bearings to prevent oxidation.

Slurry Cup

All components of the slurry cup must be cleaned and inspected thoroughly after every test to ensure proper operation of the consistometer. 1. Inspect the plug for any wear such as dishing or rounding out of the inner taper. Excessive

wear of the tapered seat will prevent the proper centering of the paddle shaft and result in binding the paddle to the interior wall of the slurry cup.

2. Inspect the shaft tip for wear and ensure that the shaft is straight. Excessive wear of the sharp tip or a bent shaft will prevent the shaft from centering in the cup base plug. Either of these conditions will result in binding of the paddle to the interior wall of the slurry cup.

3. Replace the paddle any time damage such as bent or broken vanes exists. The paddle weight should be recorded before the first use. Weigh the paddle after every 20 tests. When the original weight of the paddle has dropped by 20%, replace the paddle.

3-2 SECTION 3 – MAINTENANCE

Thermocouple (Slurry Cup)

Inspect the thermocouple to insure that it is straight and the threaded collar is positioned with two threads showing on the lower side. Inspect the threaded collar and gland nut for clean and well formed threading. Worn threading on either part presents a safety hazard to the operator. If the threads are damaged, the thermocouple may blow out under pressure. Inspect the exterior of the probe for thinning or nicking. Replace any or all components as required. Thermocouple (Oil)

Inspect the thermocouple to insure that the threaded collar is positioned with two threads showing on the lower side. Inspect the threaded collar and gland nut for clean and well formed threading. Worn threading on either part presents a safety hazard to the operator. If the threads are damaged, the thermocouple may blow out under pressure. Inspect the exterior of the probe for thinning or nicking. Replace any or all components as required.

Monthly Potentiometer Mechanism

The potentiometer mechanism must be completely disassembled and cleaned. If any of the following components exhibit signs of wear, they must be replaced as follows. Resistor Replacement

1. Remove the shaft bearing retainer and contact arm. 2. Remove the oil resistor, using care not to damage the slot. 3. Position the new resistor, straight side down, with equal overlap from the contact strips to

the end of the winding. 4. Seat the resistor firmly in the slot (use a block of wood to press into position). The

top surface of the resistor must be level. 5. Lightly burnish the resistance wire by rubbing the top surface with a hardened drill rod

shank. This will ensure that the contact arm slides smoothly. 6. Rotate the contact arm by hand. Affirm that the arm rotates smoothly and maintains

contact with the resistor from contact strip to contact strip with no dragging. If necessary, adjust the arm by bending it up or down.

7. Adjust the position of the stop arm on the center shaft in order to obtain strip-to-strip travel of the contact arm. All set screws must be tight.

8. Replace the shaft bearing retainer. 9. Calibrate the potentiometer. Calibration Spring Replacement

1. Remove the shaft bearing retainer and contact arm. 2. Remove the old calibration spring. 3. Install a new spring (when the center shaft of the potentiometer mechanism is turned

counterclockwise, the spring is wound tighter). 4. Replace the contact arm.


5. Loosen but do not remove three screws on underside. 6. Rotate the spring adjuster until slack is out of the spring and the contact arm lines up with

the contact strip. Tighten the screws. 7. Replace the shaft bearing retainer. 8. Calibrate the potentiometer.

Potentiometer Calibration

Depending on the frequency of its use, the potentiometer mechanism should be recalibrated regularly and whenever the spring, contact arm, or resistor is adjusted or replaced. Higher operating temperatures in the pressure chamber require more frequent recalibration of the potentiometer. Refer to the enclosed drawings of the calibration table assembly and Model 7322 assembly. The step-by-step calibration procedure is as follows:

1. Rotate the pot mech calibration table out to the side of the instrument. 2. Install the potentiometer on the calibration table and insert the wedge into the open slot as

shown. 3. Wrap the steel cable around the potentiometer frame and over the pulley. Place the hanger

weight hook in the cord eye. 4. Install the wire-end clips to the potentiometer tabs. (Note the wire locations.) 5. Insert the plug on the end of the calibrator wires into the calibrator socket. 6. Turn on the master switch and place 400 grams of weight on the hanger. 7. The Bearden unit gauge should read 100 Bc. (100 Bearden Units is 1 volt). The contact

points of the spring should be oiled, the weights lifted and released, and the calibrator lightly tapped to offset friction during the calibration. If the unit does not read 100 Bc, manually adjust the pot mech calibration screw located on the face panel of the top cabinet.

8. Refer to Drawing 07-0520, which is a typical calibration curve. The radius of the potentiometer mechanism is 5.2 centimeters and is multiplied by the total weight on the hanger to obtain gram centimeter torque.

9. Slurry consistency is expressed in Bearden units where 100 Bc is equivalent to the spring deflection observed with 2080 gcm of torque (400 grams weight) using the weight-loaded calibration device.

10. For further calibration details, refer to API Spec 10 booklet. This unit is supplied with weights to accommodate the full range of tests per API specs.

Magnetic Drive

The magnetic drive should be flushed with clean water or oil whenever cement spills into the cylinder or particles contaminate the drive. More frequent flushing of the drive is required when high-temperature, high-pressure tests are run. The inner magnetic shaft must be pulled and inspected. Replace the complete assembly if the magnet sleeve is worn through or bulging at the center. Remove the magnetic housing drain plug and flush all cement sediment from the cylinder using water. Dry any remaining water on the cylinder floor using towels. Inspect and replace the following components as required.


• Carbon bearing: Remove and clean all cement from the O.D. and I.D. of the bearing. Clean all cement from the external grooving. Replace the carbon bearings when excessive chipping is visible. Replace the carbon bearing if the O.D. or I.D. has lost .010” of material. The bearing must fit snugly on the shaft with no visible wobble.

• Bronze bearing: Remove and clean all cement from the O.D. and I.D. of the bearing. Clean all cement from the perimeter weep holes. Replace the bronze bearing if when the upper collar has lost .030” off its original height.

• Thrust ring: Replace the ring if a groove is present on the lower side. The lower surface should be flat with no cutting or gouging occurring from contact with the bronze bearing collar.

• O-ring & Backup ring: Replace at every cleaning or any time the drain plug is removed. • Before the center shaft of the magnetic drive is reinstalled, the drain plug should be screwed

in (but not tightened) and the drive filled with clean oil. Then install the center shaft, and pressurize the cylinder with oil (air supply pressure only) to ensure that air is not trapped in the lower part of the drive. Oil passing by the plug will purge the air.

Thermocouple and Temperature Control System

API specs require that the temperature measuring system be verified for accuracy monthly. No equipment is supplied with the unit for performing these tests. Review your API specs for details and contact Chandler Engineering.

Three Months Oil and Filter

The mineral oil in the reservoir should be drained and replaced when it becomes dirty. At the same time, the oil filter element should be replaced. A drain plug is provided on the oil reservoir, and a fill plug is located on top. Additions of mineral oil prior to oil drainage and replacement may be made by pouring oil into the pressure cylinder. The mineral oil supplied with the instrument is white technical oil (API gravity approximately 24.2, pour point 40°C, flash 214°C, and viscosity 60 to 63 SSU at 38°C). This oil may be ordered from the factory.

Drive Motor

API requires that the speed be checked and maintained at 150 rpm +- 15 rpm. A motor speed adjustment screw is located on the rear of the electrical cabinet. A tachometer for this test is user supplied.

Six Months Timer

Accuracy should be verified according to API specs every six months. There are no provisions for adjusting the timer provided with the instrument. Review your API specs for details. Air Operated Valve

1. Relieve system pressure. Remove the valve from the system and place it securely in a vice.


2. Fully open the valve stem. 3. Remove the packing gland locking device. 4. Unscrew the packing gland and remove the packing gland and stem. 5. Remove the packing from the body. Note the packing and washer arrangement. 6. Replace the packing and place the packing and packing washers into the valve body. 7. Replace the stem and packing gland, tightening to the appropriate torque. 8. Replace the packing gland locking device.

Annually Replace the high pressure filter, cylinder pressure release valve, and rupture disk.

Pump

Chandler Engineering recommends that the pump valve body be disassembled, cleaned and rebuilt by our service department. Reservoir

Chandler Engineering recommends that the reservoir be removed, cleaned out, and flushed by our service department. Heater

Chandler Engineering recommends that the heater be inspected and tested for insulation breakdown and voltage leakage, which can lead to arcing on the cylinder wall. This procedure requires the use of specialized test equipment. Insulation breakdown poses two potentially hazardous conditions: electrical shock hazard to the operator, and pitting of the cylinder at the point of arcing. Chandler highly recommends that our service department perform a series of tests on the heater at this time interval. Thermocouple and Temperature Controller

Our service department can perform a calibration procedure using specialized instrumentation to assure that temperature drift and inaccuracies as a result of time and usage are compensated for in order to keep your instrument compliant with API specs.

Model 7322HPHT CONSISTOMETER

A Critical Tool for Oil Well Cementing

An API Spec 10A compliant instrument, the Model 7322 HPHT Consistometer is designed to test cement thickening behavior under a variety of downhole conditions. Designed with laboratory efficiency and ease of operation as major goals, the Model 7322 design minimized the two largest contributors to instrument downtime: the cool-down time between tests and routine maintenance.

This popular model is designed for laboratories involved in: oil well cement research, development of cement additives, cement quality assurance and field laboratories

Engineering Excellence for Long-term Performance

A newly designed oil pressurization system employs easy-to-maintain, aerospace-inspired modular hydraulics which also eliminate oil mist. Slurry cup drive reliability is maximized by use of a magnetic coupling system to connect the drive motor to the cup. The simple to use and reliable pressure control system consists of a pump, a sensitive pressure transducer and a unique capillary pressure release unit.

Operational Simplicity and Advanced Capabilities

The usefulness of the Model 7322 Consistometer is not limited to the standard testing of cement thickening time. It can also be used to prepare slurries for other tests such as measuring free water content, testing for fluid loss or viscosity and consistency. The Model 7322 can be equipped with an external chiller for performing tests at sub-ambient temperatures.
